The unlimited mana seems only to work when all the characters are selected at the same time... (The "=" key). But since I don't want to direct all of them all the time, would there be a way the numpad 2 key, when activated, locks the mana for all your characters, selected or not? Or simply to put a instant mana regenerate for all your characters?

Note: Well, after some tests, it seems that what I want is "Party Infinite Mana"...
